4 Claims. 1

This invention relates to a wood-cutting device and it is one object ofthe invention to provide a device or this character including a troughhaving improved means at one end for holding a blade so that by placinga strip or block of wood in the trough and imparting movement theretolongitudinally of the trough a strip of the desired thickness may be cutfrom the block or strip of wood.

A further object of the invention is to provide a wood-cutting devicehaving a blade holder at one end of a trough so formed that it may beshifted vertically to adjusted position and thus dispose its blade inpredetermined spaced relation to the bottom of the trough and therebycause a strip cut by the blade to be of desired thickness.

Another object of the invention is to so form theblade holder that whenit is applied to the end of the trough and securing screws tightened,

it will befi-rmly braced against movement relative to the trough and ablade backed up and braced against movement outwardly of the trough whensubjectedto pressur as a block or strip of wood'to becut isforcedagainst the sharp inner edge of the blade.

A further object of the invention is to-provide a blade holder which maybe formed as a single casting and thus cheaply manufactured. Theinvention, is illustrated in the accompanying drawings, wherein Figure 1is a perspective view of one end portion of the trough.

Figure 2 is a perspective view of the blade holder and showing the bladecarried thereby.

Figure 3 is a perspective view showing the blade holder applied to thetrough.

Figure 4 is an end view illustrating th manner in which a strip is cutfrom a block or strip of wood.

Figure 5 is a perspective view of the upper portion of one arm of theblade holder.

Figure 6 is a, perspective view of the blade.

The trough I constituting the body portion of the wood cutter may b ofany length and width desired and has a bottom 2 and side walls 3 and 4,within the confines of which a block of Wood 6 is placed for cutting.Recexes 1 are (formed vertically in inner side faces of the walls 3 and4 at the end of the trough and extend the full height of the side wallsso that spaces 8 are provided at opposite sides of the end of the bottom2 of the trough.

In order to mount a blade 9 at the end of the trough for cutting theblock or strip 6 and forming a strip 6' of predetermined thickness,there 2 has been provided a blade holder I0 which is formed as a singlecasting and has side bars I I extending upwardly from ends of across-bar or bridge [2,. These side bars I I are of such thickness thatwhen they are engaged in the recesses of theside walls 3 and 4 ofthetrough; inner suriacesof the side walls of the trough and the sidebars will be ,flush with each other. Along their outer margins the barsI I are formed with outstanding side vflanges I2 for bearing againstends of the side walls of the'trough, and these flanges are formedwithvertically extending slots I3 through whichare passed screws-I4 carryingwashers I5 for bearingagainst outer faces of the :fiangesat oppositesidesof the slots I3 and applying clamping pressure to hold the bladeholder I 2 of the trough and when the block or strip- 6 of thisblock orstrip 6. The blade fits into slots I8 formed in the side bars II andsince these slots correspond to the width of the blade and terminate inspaced relation to outer side edges Olf the bars II, the dull edge ofthe blade will have abutting engagement with closed ends of the slotsand ends of its sharpened edge will have abutting engagement with theside edge faces I9 of the recesses I and the blade thus prevented frombecoming dislodged from the slots.

When this wood cutter is in use, it is placed upon a work bench with theend carrying the blade holder projecting slightly from an edge of thetop of the work-bench. The blade holder is adjusted to dispose the bladea predetermined distance above the bottom of the trough, and a block ofwood is then placed in the trough and shoved longitudinally of thetrough to bring an end of the block or strip 6 into contact with the 3which the invention relates will be able to obtain a clear understandingof the invention after considering the description in connection withthe drawings. Therefore, a more lengthy description is regarded asunnecessary.

Minor changes in the shape, size and arrangement of details comingwithin the field of invention claimed maybe resorted to in actualpractice, if desired.

Having thus described the invention, what is claimed is:

1. A wood cutter comprising a trough having a bottom and side walls,inner faces of said side walls being formed with vertically extendingrecesses at an end of the trough, a U-shaped blade holder having sidearms and a bridge extending between lower ends of its side arms, thebridge being disposed under the bottom of said trough and the side armsbeing slidably received in the recesses of the side walls and formedwith outstanding side flanges overlapping ends of the side walls, theside flanges being formed with vertically extending slots and the sideflanges of the trough being formed with threaded sockets, screws passingthrough the slots of the blade holder and into the threaded sockets oithe trough and carrying washers overlapping outer faces of the flangesat opposite sides of the slots for gripping the flanges and firmlysecuring the blade holder in a vertically adjusted position when thescrews are tightened, the side arms of the blade holder being formedwith slots extending horizontally from their inner side edges, and ablade extending between the side arms of the blade holder with its endportions engaged in the slots of the said arms and having a sharpenededge presented inwardly of the trough for cutting engagement with woodplaced in the trough and thrust longitudinally toward the blade.

2. A wood cutter comprising a trough having a bottom and side walls, theside walls being formed with vertically extending recesses at an end ofthe trough, a U-shaped blade holder having side arms and a bridging barbetween lower ends of its side arms, the bridging bar being disposedunder the bottom of the trough and the side arms being slidably receivedin said recesses, means for clamping the side arms of the blade holderto the side walls of the trough and releasably securing the blade holderin a vertically adjusted position, the side arms of the blade holderbeing formed with slots leading from their inner side edges, and a bladeextending horizontally between the side arms of the blade holder withits end portions engaged in the slots thereof, and said blade having asharpened edge presented inwardly of the trough for cutting engagementwith wood stock placed in the trough and shoved longitudinally towardthe blade.

3. A Wood cutter comprising a trough having a bottom and side walls, ablade holder including bars disposed vertically against ends of the sidewalls and shiftable vertically along the same to adjusted positions,means for securing the bars in vertically adjusted positions upon theside walls, said'bars having slots leading from their inner side edges,and a blade extending between the bars with its ends engaged in theslots and its sharpened edge presented inwardly of the trough.

4. A wood cutter comprising a trough having side walls formed withvertically extending recesses in their side faces at one end of thetrough, a blade holder having portions fitting into said recesses andformed with horizontal slots leading from their inner side edges andother portions abutting ends of the side walls and formed with verticalslots, a blade extending between the pertions fitting in the recessesand having its ends engaged in the horizontal slots thereof, andfasteners p ssed thr ugh the vertical slots of the blade'holder andscrewed into threaded sockets formed in the side walls of the troughand, when tightened, applying clamping pressure to releasably secure theblade holder in a vertically adjusted position.
